The population in these standard metropolitan areas increased from 83.8 million to 95.3 million, an increase of 13.7 percent, whereas there was little change in the population outside these areas (table A). Within the standard metropolitan areas, the rate of growth in the outlying parts was seven times as rapid as in the central cities (27.8 vs. 3.8 percent). These data reflect a continuation at an accelerated pace of the trends which characterized the decade 1940 to 1950. Table A.--CIVILIAN POPULATION OF THE UNITED STATES, BY METROPOLITAN (Minus sign (-) denotes decrease) percent, whereas the population living in urban territory outside the central cities rose by 4.5 million, or 19.1 percent. Undoubtedly, much of this formerly rural territory has been built up since 1950 and would qualify for inclusion as urban. In the territory outside the standard metropolitan areas, the urban population increased by 5.0 percent to 24.2 million. The rural population, on the other hand, declined 1.9 percent to 41.9 million. URBAN AND RURAL RESIDENCE BY AGE Although there were marked differences in the rates of growth in the urban and rural population inside and outside standard metropolitan areas, the rates for all urban and all rural areas were identical. The increase of 7.6 million in the urban population was at the rate of 7.9 percent, as was that of 4.3 million in the rural population (table B). The only broad age group which showed a decline was that 15 to 29 years. This age group declined 2.3 million, or 7.0 percent, with the rate in the urban population exceeding that in the rural population (8.2 vs. 4.8 percent). The decline in this age group is attributable to the low number of births during the depression years and, for the males, the increase in the Armed Forces over the 5-year period. SEX RATIO females As in 1950, there was an excess of in the urban population and an excess of males in the rural population (table D). In the urban population, the number of males per 100 females declined from 93.5 to 91.1 over the 5-year period. In the rural population, the number of males per 100 females dropped from 104.4 to 102.9. For the total population, the decline in the number of males per 100 females was from 97.3 in April 1950 to 95.0 in April 1955. This decline in the sex ratio for the total civilian population is attributable in part to the higher mortality rates of men and in part to the increase in the size of the Armed Forces. RURAL POPULATION BY FARM RESIDENCE The excess of males living on farms continued. In the rural-farm population there were 108.6 males for every 100 females. In the rural-nonfarm population, on the other hand, the sexes were nearly in balance; here there were 99.7 males per 100 females. A higher proportion of the rural-nonfarm population than the rural-farm population was under 5 years of age--13.2 as against 10.6 percent. The estimated number of children under 5 years of age per 1,000 women 20 to 44 years of age in the rural population, however, did not differ significantly between farm and nonfarm residents. The data shown here for the rural-farm population for April 1954 differ from those for the farm population which appear in the report Farm Population, Series Census-AMS (P-27), No. 20. The farm population in the latter report includes the urbanfarm population as well as the rural-farm population. The farm population shown in the Series P-27 report also includes members of the Armed Forces included in the survey who were living on farms. DEFINITIONS AND EXPLANATIONS Population coverage.--The data for April 1955 shown in this report relate to the civilian population of the United States, exclusive of all members of the Armed Forces. The figures for the total population are based on independent estimates of the civilian population; their distribution by urbanrural residence is based on data obtained in connection with the Current Population Survey of the Bureau of the Census. The April 1950 data were derived from the 1950 Census of Population by excluding members of the Armed Forces. In addition, the age groups 55 to 69 years were adjusted for apparent age bias in the nonwhite population. For a discussion of this bias and the size of the adjustments, see Current Population Reports, Series P-25, No. 101. Urban and rural residence.--The territory classified as urban in the April 1955 survey is the same as that in the 1950 Census. According to the definition used in the 1950 Census, the urban population comprises all persons living in (a) places of 2,500 inhabitants or more incorporated as cities, boroughs, and villages, (b) incorporated towns of 2,500 inhabitants or more except in New England, New York, and |
